Joris Van den Bossche updated ARROW-6778:
-----------------------------------------
Description:
Currently, duration is not yet supported in basic cast operations (using the
python binding from ARROW-5855, currently from my branch, not yet merged):
{code}
In [25]: arr = pa.array([1, 2])
In [26]: arr.cast(pa.duration('s'))
...
ArrowNotImplementedError: No cast implemented from int64 to duration[s]
In [27]: arr = pa.array([1, 2], pa.duration('s'))
In [28]: arr.cast(pa.duration('ms'))
...
ArrowNotImplementedError: No cast implemented from duration[s] to duration[ms]
{code}
